Cat had no doubt that the man standing in the middle of the kitchen was the Dark Stranger. Cats sister Gwendolen had been told by a fortune-teller that she was destined for great things, and that a  dominant Dark Stranger would have something to do with it. So it was hardly surprising that when Cat saw the tall, dark, well-dressed man standing in the kitchen he thought it was Gwendolens Dark Stranger come to help her start ruling the world. Sometimes it was a trial being the brother of a powerful witch especially when you had no magical gifts yourself.
